초록

Although Asbestos is extremely harmful carcinogen, there remain many buildings in. Especially unsheltered asbestos cement slate should be removed in the near future because they will be possible scattering and polluting. Complete enumeration surveying is definite way but there are too difficult situations to depend on pure labor. So on the study carry out research using UAV, targeting housing redevelopment area where is scheduled to be dismantled and demolished, identification roof type and verification on field. For the purpose of this study, take photographs by low altitude flight and create orthophoto on photogrammetry application based on point cloud. Orthophoto has made sure of location accuracy within GCP's coordinates by RTK-VRS equipment. Total RMSE is less than standard error limit. And Ground Sample Distance of orthometric corrected image is 1cm/pixel which has enough resolution to identify roof type. Upon analysis, 53 roofs are verified slate and the others 246 are not by orthophoto analyzation. Then drawing a parallel result between orthophoto and building ledger. 20 in 53 slate roofs correspond with each other but the other 33 roofs are different type. Such as differences have verified through on-site reviewal. Also, As a result of identification and verification have shown usefulness that technical method. The process of identifying asbestos cement slate using UAV could be a useful research technique. Also, In the future, the methodology of this study is expected to be used as a technique to complement and improve the existing asbestos survey methods.
